The Average Weekday Traffic Volume is a count of the number of vehicle axle pairs (a car has 2 axles) passing through a given location on an average weekday. This is the traffic volume over a one-day weekday period and is a summary of the data that is collected in 15-minute intervals. The 15-minute interval traffic volumes for a particular location are available through Mesa’s Interactive Traffic Count Map application at https://gis.mesaaz.gov/TrafficCounts
